Spaces as default or global config

[tiagovla]

So far, the transition from lua-format to stylua was flawless.

My only issue is that I need to configure it for every project because it uses tabs as default, unlike lua-format. Is there a particular reason for that?

It would be nice if it would:

1. search for local config
2. fallback to global config (maybe inside ~/.config/stylua.toml)
3. fallback to default config

It's great to hear that the transition went smooth!

it uses tabs as default, unlike lua-format. Is there a particular reason for that?

StyLua is designed around the following style guide: https://roblox.github.io/lua-style-guide/, in which case Tabs are set to default. It is unlikely that will change.

fallback to global config (maybe inside ~/.config/stylua.toml)

I'm against this behaviour for the same reasons I described in
#127 (comment) - if you are working with other developers for a repo and it uses default StyLua (no config file in project), and you change from the default config in a parent/global config, then the changed config you applied would be used, rather than the formatting for the project, which is unwanted.
One thing I could do, however, is to introduce a CLI flag e.g. --search-parent-directories or similar. In this case, we would look for the config in a parent directory, or in the e.g. XDG_CONFIG_HOME. This will provide the functionality you want, whilst keeping the original behaviour as default. How does that sound?

Great!

@JohnnyMorganz I want to point out that the guide is underspecified, as it does not define the tab length and rather make rules based on assumptions.
Further I would have expected from the guide to take into consideration that tab settings are an additional and inconsistent editor configuration.

If you want to have some glory editor examples not a tab width of 4 here.

And this does not even take into consideration other messed up technology having different tab-length or requiring explicit configuration.

[JohnnyMorganz]

StyLua uses indent_width as the definition of a single tab width, and a single tab is used per indentation.

I'm not sure what the guide states specifically, it is the inspiration for this formatter, but not necessarily the defining specification.

I think, to not get into a debate about tabs vs spaces, the option is open for configuration for a project, they don't need to force tabs if they don't want it. Personally, tabs are important to me for accessibility reasons
